The length of a list in Python is the number of elements in the list. We can use the len() function to get the length of a list.
For example, consider the following list:
my_list = [10, 20, 30, 40, 50]
To get the length of this list, we can use the len() function:
print(len(my_list)) # output: 5
In this case, the length of the list is 5, since it contains 5 elements.
Note that the len() function can be used with other data structures in Python as well, not just lists. It returns the number of items in any iterable data structure.
